The Gulf of Cariaco is an enclave located in the state of Sucre, in eastern Venezuela, with great ecological importance because it houses a high diversity of ecosystems, several of which are used by many species as breeding grounds. Different studies have been done to determine the composition of the biota in the spaces of this body of water, but few have been directed at the presence of exotic species, something that threatens its biodiversity. In this regard, a brief review is presented of the records of non-native species in the gulf, of those that could be occupying these waters and the first record for this area of the mollusk Narias turdus, a taxon originating from the Red Sea, the Gulf of Oman and East Africa in the Indian Ocean. The discovery was made in the town of Camacuey, near the city of Cumaná. The species is distinguished by its oval-shaped shell, strong, smooth, shiny, with irregular light brown, dark brown and ochre spots, scattered dorsally and laterally, on a whitish-greyish surface; with a thick, white base, with irregular light brown, dark brown and ochre spots. The occurrence of specimens of various sizes suggests that it has not been a recent settlement and the possibility that it is in other areas of the gulf.
